Step 2: Once steady state minimum desired operating flow is
obtained, perform the 'Teach' function on the flow switch. The
'Teach' function is initiated by holding down the minus '-' button
on the face of the flow switch for 15 seconds. During this 15
second period, LEDs '0' and '9' will be lit green. Once the
'Teach' function is completed, the outer LEDs will flash green
as shown in Figure 30.

Step 3: After the 'Teach' function is completed and the outer Figure 31: Teach Adjustment Complete
LEDs flashed, the flow switch will indicate a new set point
based upon the current flow which should still be at the steady
state minimum desired operating flow.Figure 31 shows a
typical display for this condition. All LEDs to the left of the
SP LED are lit green. The SP LED is lit RED (or may toggle
amber) which indicates that the flow switch is OPEN. Typically,
an increase in fluid flow is between 15% to 30% above the
'Teach' function flow is required for the SP LED to turn AMBER
and the flow switch to CLOSE indicating acceptable flow.
